Japanese way of walking to school - like ducks in a row

When i am riding to school, i often see the elementary school students walking to school. And i am always amazed at how much like ducks they look. There is always one older student who walks at the front with a flag and then the rest just follow. It is like a mother duck with her babies following. So cute. So before i left i had to get a photo of it. So here it is...............these are in the danchi.
